T aZZ whom/it mayconcern: Y Be it known that LJoHN W. Evans, ofCleveland, Ain the county of Cuyahoga and State of Ohio, haveinventedcertain newland use-V ful Improvements in Percolators; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the artzto which itpertains to make and use the same.

My invention relates to improvements in percolators designed moreespecially for the extraction of cotton-sced oilbythe naphtha process.

My presentinvention isdesigned as an improvement on-a pcrcolator forwhich Letters Patent of the United States No. 245,365 were granted to meAugust 9, 1880.

My formerpercolator, patented as aforesaid,

ywas of considerable height, usually twelve feet or more in the clear.Inside of the percolator was a series of radial arms or so-calledbreakersj having steam-pipes attached underneath. The breakers were supported'at' theirinner ends by a center piece, and the outer ends werehinged tobrackets, the latter being secured vto the walls of thecontainer some five or six feet from the bottom of the latter. Thebrackets had hollow trunnions that connected with the correspondingchambers-in the breakers, and so arrranged that the perforated`steam-pipe connected with the breakers and the supply-pipe connectedwith the brackets were in open relation. By depressing the center.support the breakers and,

,them'of such a large diameter as will give the necessary capacity. Itis also found ltobe nec- .essary to provide additional breakers locatedon a lower Yplane and cross-bars located still lower, each havingperforated steam-pipes attached tointrodnce steam into the central andlower'portion of the mass. A `slightlyconical false bottom is-made of,perforated plate, and betweenthe perforate and imperforate bottoms islocated a heating-coil. A

system of pipes leading up throughk the bot tom of the percolator isarranged with suitablenvalves andl branch pipes, bymeans of y whichthese ypipes are used to admit steam for g heating, and are also usedfor drawing ofi' the oil. Various other improvements are had in thedetails of constr11`ctior1,whichr arejmore `clearly'showninl theaccompanying drawings. s

Fig. 10 is a bottom `plan ofthe block H. Fig. llis an'elevatio'n in sec'- f tionof the block H. y 1A represents the container vor body ofthe percolator, and is madeusually of heavy boilerplate'and mounted non legs A. The container i hassubstantially a flat bottom, A?, and a conical top, A3 the latter beingprovided atthe apex with a large man -hole and man-hole platelThe'flange a varoundthe. many hole is of considerable depth to make roomfor a cross-bar, a, that is secured to the'inside of f itheilange out ofthe wayofthegcover. The" cross-bar supports the centerpiece,hereinafterldescribed. -The cover ais 'usually threevorl vfourfeet in diameter,andis consequently too` v heavy to handle. Ihave thereforeprovided a 1,A Ico sisting of a rail, lsupported on legs B', .thel l' or cover, a.

tramway for moving this cover, the same con# latterfbeing attached tothe top A3 ofthe per1 y the right hand. Fig. 7 is anyelevation in translf colator. A iianged carrying-wheel, b, travels on the rail, and theyoke of the wheel hasa depending swivel-bolt, b', that screws into thecenter of the cover a, by means of which the cover may be raised fromits seat and carried to one side on the tramway. The container isprovided with one or more doors, A4, usually two in number and locatedon opposite sides. These doors reach to near the bottom of thecontainer, and are usually three or four feet square, more or less, sothat work-j` men can easily enter the doorway for shoveling out thecontents of the container. Some distance above the line of the door is alarge steam-pipe, C, that encircles the container, and from which branchpipes lead into the container at different points-to wit, the pipes clead'to the breakers D, and the pipes c to the breakers E, and the pipesc2 to cross-bars F. The breakers D are hinged to the brackets D', thelatter being secured to the container inside thereof. rlhe brackets andtrunnions of the breaker are chambered with suitable 'openingsconnecting the chamber when the breakers are in a horizontal position.The chamber in the bracket is connected with the pipe c, and the chamberin the breaker is connected with a perforated pipe, d, that is securedto the under side of the breaker. The breakers at the inner end aresupported by a center piece, D2,

' the latter being supported by a chain, d', that eter.

is detachably secured to the cross piece a. When the parts .are inWorking position, an open passage way is had from the pipes c throughthe chambers of the bracket and breaker t'o the pipes d. When the centerpiece D2 is lowered, by unfastening the chain the brackets D can turndown by the side of the container. These breakers are arranged so thatnone of them come in front of the doors. The breakers D and attachmentsare substantially the same as were described in my patent aforesaid, andtherefore it is not considered necessary to give a more detaileddescription of them in this specification.

The breakers E arelocated on a lower plane, and consequently have to beshorter than the brackets D in order to fold down inside. The centerpiece E3, that supports these brackets, is, therefore, correspondinglylarger in diam- The `brackets E2 have perforated pipes e attached, andare arranged substantially the same as the bracket D, except that abreaker E comes in front of a door and when turned down would be in theway. I have therefore made these breakers that are in front of the doorwith a trunnion, E', on either side, and the brackets E2 are bifurcatedto receive the breakers and have only half-boxes to receive thetrunnions, as shown in Figs. 5, 6, and 7.

The trunnions and bearings of the brackets have ground joints, by reasonof which the weight of the bracket and of the material resting on thebracket is suicient to hold the breakers down to their seats in thebracket and form a steam-joint. When these breakers are turned down,they may be lifted out of the brackets and removed. The pipe e is inopen relation with the pipev c when the breakers are in a horizontalposition. The center piece Ea is supported by a chain, e",that isattached to the center-'piece D2.

Perforated pipes e are loosely secured to the part E3, so as to bemovable endwise. The pipes e are provided, respectively,with couplingse2, the outer end of which is made large enough to slip onto theunthreaded inner ends ofthe pipes e. Of course such joints will leaksteam more or less; but in place of such leakage doing any damage itonly saves perforating the pipe at this part. On a plane about midway ofthe height of the doors, or perhaps a trifle lower, are located thecross-bars F. These bars are supported at their outer ends byangle-plates F and are supported at the center by the shoulder g of thestand-pipe G.

The bars F have respectively attachedv un: derueath perforated pipes f,the latter having elbowsf at the outer ends that present downwardandengage the upturned elbows on the pipe c2. cal and the end of theopposing elbow is made correspondingly concave, forming what is known asballand-socket7 elbows. These joints are of course ground together, andthe pipef stands olf from the bar F, so as to cause the elbows to bepressed firmly together when the bar F rests on the supportingangle-plate. The pipe c2 is branched, as shown in Fig. 3,0m the outsideto lead to the two bars F that are supported from the door, and abovethe door the pipe c2 is provided with a sleeveunion, c, by looseningwhich the pipes connected with the door are removed Vwith the door. Atthe point 0*,where the branch pipes c2 join the main pipe, a shortperforated pipe may lead through the door and discharge steam justinside the latter. The standard G is per- The end of one elbow is madeconiforated and rests on a hollow block, H. The

latter is shouldered on top, and the central portion extends up into thepipe G a short distance to hold the latter in position. The block Hisheld in place by dowel-pins h. This block,on the bottom side,haschannels h' leading into the central hole of the block,through whichchannels oil can be drained from the container.

' Perforated plates I rest on the bottom A2 at the inner periphery ofthe container, and the inner ends of these plates rest on the shouldersh2 of the block H. Between the bottom A2 and the plates I are locatedcoils of pipe-J for heating. A large pipe, K, is secured, usually bymeans of a flange, to the under side of the container in position toregister with the passageways through the blocks Hand stand-pipe G.

The pipe K has a valve, K', and a manifold, K2, and branches L and L',the latter having, respectively, valves Z and Z'. From the manifoldleads the pipes J', that connect with the coil J, and the pipes m, thatlead up through the bottom of the container, near the periphery of thelatter. These pipes are provided,

respectively, with valves j and m.' The pipe IIO r381,062 1" f I c 1.
